Energy and spectrum efficient user association in 5G heterogeneous networks
(Institute of Electrical and Electronics Engineers (IEEE), 2016)
Text en actes de congrés
Accés restringit per política de l'editorialDue to the dense small cell deployment to cope with the increased data traffic of fifth generation (5G) networks, the direct backhaul (BH) connection of all small cells to the core network becomes challenging. To that end, ... -
Energy and spectrum efficient user association in millimeter wave backhaul small cell networks
(2017-02)
Article
Accés obertMacrocells are expected to be densely overlaid by small cells (SCs) to meet increasing capacity demands. Due to their dense deployment, some SCs will not be connected directly to the core network, and thus, they may forward ... -
Energy efficiency analysis of secondary networks in cognitive radio systems
(2013)
Text en actes de congrés
Accés restringit per política de l'editorialIn this paper, we evaluate a novel contention-aware channel selection algorithm that focuses on energy efficiency improvement of a secondary network (SN) in a scenario where other non-cooperating SNs are also using the ... -
Energy impact of outdoor small cell backhaul in green heterogeneous networks
(2014)
Text en actes de congrés
Accés restringit per política de l'editorialSmall cells (SCs) are expected to be densely deployed during the next few years to enhance the network capacity of future heterogeneous networks (HetNets). Due to their dense deployment, not all SCs are expected to have a ... -
Energy-efficient context-aware user association for outdoor small cell heterogeneous networks
(2014)
Text en actes de congrés
Accés restringit per política de l'editorialTo meet the ever-increasing traffic demands, future cellular networks are about to include a plethora of small cells (SCs), with user equipments (UEs) being able of communicating via multiple bands. Given that SCs are ... -
Energy-efficient user association in cognitive heterogeneous networks
(2014-07)
Article
Accés restringit per política de l'editorialDue to the ever increasing data traffic demands, which are directly connected to increased energy consumption, it becomes challenging for operators to achieve capacity enhancement while limiting their electric bill. To ... -
Joint uplink and downlink cell selection in cognitive small cell heterogeneous networks
(2014)
Text en actes de congrés
Accés restringit per política de l'editorialIn the next few years, small cells (SCs) are about to be densely deployed to achieve sustainable capacity enhancement. Due to the expected high SC density, some SCs will not have a direct connection to the core network, ... -
Nonuniform traffic distribution model in reverse link of multilaterate/multiservie WCDMA/based systems
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2007-09)
Article
Accés obertThis paper focuses on the modeling of the reverse link of a wideband code division multiple access system in a nonhomogeneous environment with a single cell. Multiple traffic spatial and service nonuniformities are considered ... -
Using simulation to provide alternative solutions to the flowshop sequencing problem
(2010)
Text en actes de congrés
Accés obertIn this paper we present SS-GNEH, a simulation-based algorithm for the Permutation Flowshop Sequencing Problem (PFSP). Given a PFSP instance, the SSGNEH algorithm incorporates a randomness criterion to the classical NEH ...
